Choosing among Shopify Plus agencies means looking beyond the storefront. For an established brand, the brief may also involve app connections, product data, migration risks, and post-launch support.
This shortlist is for US ecommerce teams planning a redesign, migration, or custom development project, including Dallas-Fort Worth readers. We aren’t presenting these agencies as local firms, and we compare them on published services, project examples, support, and pricing visibility.
Key Takeaways
- Weberous is our top pick for custom-coded storefronts, integrations and ongoing support, backed by its Shopify Plus partner status and FEATURE project.
- Avex fits brand-led redesigns that also need search, merchandising and repeat-purchase programs.
- Absolute Web merits consideration for projects involving back-office systems, Shopify apps and B2B development.
- Swanky suits subscription commerce and international expansion, including brands serving the US and Canada.
- Barrel focuses on consumer packaged goods, with services spanning content, commerce and retention.
- Eastside Co combines theme-based or bespoke development with marketing and ongoing support.

How we picked
We used agency service pages, project write-ups and available directory listings. We did not hire, test or interview the agencies, and because ratings, project details and agency-reported store counts are different evidence types, we haven’t combined them into a score.
Relevant work and specific services. We looked for Shopify or Plus projects and named deliverables, including custom builds, app development and API connections, rather than broad design claims.
Integration and support evidence. We checked named integrations, migration services and post-launch arrangements. That included tickets, tracked hours and scheduled development work.
Commercial clarity. We assessed whether published prices identify a service. Directory figures are selected-service starting points, not typical budgets or complete Plus quotes.
Before requesting proposals, name your required integrations and clarify custom versus adapted-theme work. Assign responsibility for migration, SEO and support at the same time.
Platform fit also needs checking. Shopify made native B2B features available on its Basic, Grow and Advanced plans on April 2, 2026, including up to three active B2B catalogs, so wholesale alone doesn’t establish a need for Plus.
Shopify Scripts stopped executing on June 30, 2026. Ask any agency how it moved older checkout logic to Functions or public apps.
Weberous
Weberous pros
- Shopify Plus partner agency and one of the first Shopify Experts
- Custom-coded storefronts, built without templates or themes
- Custom app development and app integrations, with feasibility explored for each idea
- SEO guidance and maintenance support alongside design and development
- Case studies including FEATURE and Jeffree Star Cosmetics
Weberous cons
- A fully custom build can take longer than a theme refresh
- No ready-priced Plus package is listed, so budgeting starts with a scoping conversation
Why we picked Weberous
Weberous is our top pick for a distinctive storefront that also needs integrations and ongoing care. The Los Angeles agency pairs custom design and app work with SEO guidance and maintenance, which gives us concrete reasons to put it first for that brief.
Our research experience with Weberous
We were especially drawn to the FEATURE case study, which pairs storefront design with a custom release and raffle platform. That gives merchants a concrete project to discuss when a release process needs more than a storefront layout.
Its case studies also include Jeffree Star Cosmetics, and its Shopify Plus page connects app integrations with SEO and maintenance support. Together, those details make it a compelling first conversation for brands seeking custom design backed by ongoing technical support.
Weberous pricing
Weberous scopes Shopify Plus work by proposal. Ask for separate line items covering storefront design, development, migration, custom app work and ongoing support.
Keep Shopify’s subscription and third-party app charges separate from agency fees. Confirm deliverables, taxes, currency and recurring charges before comparing proposals.
Avex
Avex pros
- UX/UI design and Shopify migration services
- Retention work, including loyalty and reward programs
- Conversion rate optimization and international expansion support
- A process spanning discovery, ongoing support and optimization
- Documented Algolia integration for NAKEDCASHMERE’s search and merchandising
Avex cons
- Its discovery-led approach may exceed what a narrow theme edit needs
- The $10,000 directory starting figure covers selected services, not a complete Plus build
Why we picked Avex
Avex takes the second slot for brands whose redesign brief includes merchandising and repeat purchase. Its published services connect Shopify development and migration with design, conversion optimization and retention work.
Our research experience with Avex
The NAKEDCASHMERE write-up gave us a concrete example of that combination. It describes a Shopify Plus redesign with an Algolia integration for search and merchandising, without claiming a conversion uplift.
Avex shows 5.0/5 in Shopify’s Partners Directory from 4 reviews, which is a small sample rather than a prediction of project results. We’d use the case study to discuss how search, product discovery and loyalty fit the same brief, and checkout friction and cart abandonment belong in that conversation too.
Avex pricing
Shopify’s directory lists selected services starting from $10,000. That figure doesn’t establish the cost of a complete Shopify Plus implementation, a typical project budget or a monthly retainer.
Ask which deliverables the starting figure covers and request a quote for your full redesign and retention scope.
Absolute Web
Absolute Web pros
- Documented integrations with ERP, CRM, PIM and OMS platforms
- Named connections including Recharge, Signifyd, Narvar and Bloomreach
- Migration services, custom Shopify apps and B2B development
- Published support model with weekly sprints, monthly scorecards and quarterly roadmap updates
Absolute Web cons
- For a systems-heavy brief, confirm which team owns each integration and its maintenance
- Build and migration starting figures cover separate services, so comparing the full scope takes care
Why we picked Absolute Web
We’d shortlist Absolute Web when the project’s complexity sits in the systems behind the storefront. Its published Shopify services address connections to business software alongside app development, migration and B2B requirements.
Our research experience with Absolute Web
Its service page names ERP, CRM, PIM and OMS integrations, which is more specific than a general promise to connect apps. We also found a described support rhythm of weekly sprints, monthly scorecards and quarterly roadmap updates.
The agency shows 4.9/5 in Shopify’s Partners Directory from 38 reviews. We’d still confirm response commitments in the contract.
Absolute Web pricing
Shopify’s directory lists store build or redesign starting at $30,000 and store migration starting at $50,000. These are starting figures for distinct services, not a combined total or a complete Plus quotation.
Swanky
Swanky pros
- A published service offering for US and Canadian brands
- Subscription commerce design and development
- Support for international expansion, including entry into North America
- Design and development paired with ongoing growth services
Swanky cons
- Confirm working-hour overlap and meeting cadence for a US team
- No verified comparable full-project price was available
Why we picked Swanky
Swanky’s published services fit subscription commerce and cross-border expansion. Its North American offering makes it relevant to US merchants despite its UK headquarters.
Our research experience with Swanky
We found explicit support for global brands entering the USA and Canada, alongside design, development, subscriptions and growth services.
Swanky announced a £7.6m investment from YFM Equity Partners on April 28, 2026. We treat that as business context rather than evidence of delivery quality.
Swanky pricing
We didn’t capture a verified project price for Swanky. Request a proposal separating the launch build, subscription work, international requirements and ongoing growth support.
Barrel
Barrel pros
- Focus on consumer packaged goods brands
- Shopify builds and migrations, including the reported Sweet Loren’s project
- Customer research and conversion rate optimization
- Subscription and retention services, including email campaigns
- Single-project and monthly workstream engagement options
Barrel cons
- Its CPG emphasis is a narrower fit for merchants outside that category
- Shopify’s directory doesn’t provide a fixed project total
Why we picked Barrel
We’d consider Barrel for a consumer packaged goods brand that needs commerce, editorial content and repeat-purchase programs planned together. Its services span research, Shopify development, subscriptions and retention.
Our research experience with Barrel
The Sweet Loren’s migration gives a specific example of its published scope. According to its Shopify partner profile, Barrel moved products from WooCommerce to Shopify 2.0, with 300+ blog posts included in the migration.
That describes project scope rather than an audited result. We’d use it to ask who maps editorial content and checks the finished pages.
Barrel pricing
Barrel describes single projects and monthly workstreams, but its services page lists no numeric fees. Shopify’s directory directs prospects to contact the agency for pricing.
Request separate scopes for the build and any recurring work.
Eastside Co
Eastside Co pros
- Development ranging from theme adaptation to bespoke builds
- Marketing alongside design and development
- Shopify app development
- Ongoing design and development support with flexible, trackable hours
Eastside Co cons
- The proposal should distinguish an adapted theme from a bespoke build
- No comparable project or monthly support price was verified
Why we picked Eastside Co
Eastside Co rounds out the shortlist for merchants seeking development, marketing and ongoing support from one agency. Its US-facing page describes those services alongside app development.
Our research experience with Eastside Co
The published range from theme-based to bespoke work makes the build approach an essential proposal question. Eastside Co’s US service page claims more than 500 Shopify stores built, an agency-reported count we couldn’t independently audit, so ask which builds were bespoke.
Eastside Co pricing
We haven’t supplied an unverified project amount or reused support-package prices from older lists. Request separate scopes for the build and ongoing support.
Confirm the build approach, recurring charges and whether unused support hours roll over.
Conclusion
Weberous is our top pick for an established brand seeking a custom-coded Shopify storefront with integrations, SEO guidance and post-launch maintenance. Its Shopify Plus partner status and FEATURE release platform give that recommendation a concrete basis.
Avex is our runner-up for a redesign centered on brand experience and retention. We’d consider Absolute Web for systems-heavy integration work, Swanky for subscriptions and international expansion, Barrel for content-heavy CPG commerce and Eastside Co for development combined with marketing and support.
Send the same scope to every agency on your shortlist and ask each to identify deliverables, migration responsibilities and post-launch ownership.

What happened to Shopify Scripts?
Shopify Scripts stopped executing on June 30, 2026. Custom checkout logic now runs through Shopify Functions or public apps.
How much does a Shopify Plus agency cost?
Published figures vary by service. In this comparison, directory starting points range from $10,000 for selected services to $50,000 for a store migration, and the other agencies quote by proposal.
What should I ask before hiring a Shopify Plus agency?
Ask whether the build is custom or theme-based, who owns each integration and how post-launch support is tracked. Request itemized proposals so you can compare like for like.
